Collecting Measurement Data from Devices

Determining which Device(s) to Use

When a ServiceRequest referenced from a citizen’s CarePlan has status set to active, it is expected that any required measurement device has been provided to the individual expected to perform measuring. Typically but not necessarily this individual is the citizen. Once provided, the following FHIR resources are created or, for the first two, reused:

• FHIR Device representing the particular device instance

• FHIR DeviceMetric representing state and details about the particular device instance

• FHIR DeviceUseStatement which establishes relationships between the Device, Patient, and CarePlan.

Determining when to use the same Device simultaneously for multiple measurements

When the same Device is expected to be used for multiple, different measurements, the citizen’s CarePlan references a PlanDefinition where an activity group in the PlanDefinition (or its possible sub-PlanDefinition(s)) has code SDG (Same Device Group).

An activity group is represented as a PlanDefinition.action which has sub-activities defined as PlanDefinition.action.action. As per the recursive construct of PlanDefinition.action.action, an activity group can be nested, in principle at any nesting level. A Same Device Group is a PlanDefinition.action or PlanDefinition.action.action with code set to Coding with code = SDG, system = http://ehealth.sundhed.dk/cs/activitydefinition-code (see ActivityDefinitionCodes).

All the sub-activities of a Same Device Group are expected to be measured using the same device simultaneously.
